Zimmermann 150.3441.54 Disc Brake Rotor - Front or Front Left

Brake Rotor for BMW Applications

The Zimmermann 150.3441.54 is a slotted disc brake rotor built for BMW fitments that require a 348 mm front rotor with a 30 mm thickness. Its coated surface and high-carbon machining support corrosion resistance and consistent braking performance in wet conditions.

Compatible With BMW X1 and BMW 335i applications, this rotor uses a grooved braking surface to help move brake dust and water away from the contact area. The Black Z design adds a performance-oriented appearance while maintaining the dimensional requirements of the original application.

Key Features

• Slotted brake disc design for improved surface cleaning during braking.
• Coated finish for added corrosion resistance.
• High-carbon machining for stable rotor construction.
• 348 mm outer diameter with 30 mm thickness.
• 6/5 hole arrangement, 120 mm bolt circle, and 79 mm hub bore.
• Zimmermann Black Z rotor line with a performance-focused appearance.

Detailed Description

The Zimmermann 150.3441.54 brake rotor combines standard rotor development experience with track-informed engineering. Its grooved braking surface is intended to expel brake dust and water more effectively, which supports wet-weather braking consistency. The coated surface helps protect the rotor from corrosion, while the high-carbon construction supports dependable thermal behavior under repeated braking.

This part cross-references BBB Industries 17803 and Four Seasons 44050 for the same application. It fits BMW X1 and BMW 335i front applications, including BMW 335i xDrive and BMW 335is front fitments listed in the catalog data. The part number 150.3441.54 is also associated with the Black Z rotor family, which is identified by its coated finish and slotted surface.

What It Is Used For

• Replacing a worn or warped front brake rotor.
• Restoring braking smoothness when rotor surfaces are uneven.
• Addressing brake noise caused by rotor wear or surface damage.
• Improving water and dust evacuation from the braking surface.
• Maintaining correct rotor dimensions for BMW front brake service.

Installation Notes and Tips

Verify rotor diameter, thickness, hub bore, bolt circle, and hole arrangement before installation. Confirm the vehicle’s front fitment and match the catalog notes for BMW X1, BMW 335i, BMW 335i xDrive, BMW 335is, and BMW 335xi applications. The paired article number is 150.3441.55, which should be checked when servicing the opposite side or related axle position.

Quality Assurance

Zimmermann states that the Black Z rotor range is ECE R90 homologated where applicable, and the product is not subject to registration when that approval applies. The rotor is built with coated, high-carbon construction to support corrosion resistance and consistent braking performance.
